Why does lshw command on ubuntu shows me ram information different from what I see on my ram when opening my laptop?
When using lshw command to verify my ram info it shows that i have:
SODIMM DDR3 Synchronous Unbuffered (Unregistered) 800 MHz (1.2ns)
But when i open my laptop I see that i have:
2GB 1R×16 PC3L-12800S-11-13-C3
I am using Ubuntu 20.04 The ram vendor is Samsung
When googling i found that ddr3 is the same as pc3 and ddr3l is like pc3
The other slot contains hynix ram stick which shows me also the same thing (DDR3)
I hope the screenshots are visible
The laptop is lenovo G50-45

DDR3 or PC3 is the Standard Voltage memory module that operates at 1.50V (JEDEC compliant).
DDR3L or PC3L is the Low Voltage memory module that operates at 1.35V (JEDEC compliant).
These look the same to lshw. The only difference, in most cases, is the operational voltage.
sudo lshw -C memory shows that you have 4G RAM total. That's two 2G DDR3L or PC3L SODIMMs.
Technically your computer uses the L variant.
